ENERGY: California added the most wind energy to the grid in 2011

California added 921 megawatts of wind power to its electric grid last year, the most additional wind power of any state, according to the Department of Energy.

California now has 3,917 megawatts of wind power on its grid, third among all states but well behind Texas, which has 10,294 megawatts. A megawatt is enough power for 650 typical homes.

California's three investor-owned power utilities ---- San Diego Gas & Electric Co., Southern California Edison and Pacific Gas & Electric Co. ---- must provide 33 percent of their power from renewable sources such as wind and solar by 2020.
